Lightroom CC: Main photo detail view freezing

Occasionally in Lightroom CC (i.e. the new cloud one!) the main photo view - i.e. the large detailed one when you select a single image - freezes up. If you click on the Photo Grid or Square Grid, both keep working fine, but there is nothing you can do to get Detail photo to reappear apart from restart Lightroom CC.

I've now worked out that this happens when I delete an image from detail view, and then flick back through the photos, passing through the deleted image (which takes a few moments to vanish from Lightroom). When you go past the deleted image the detail frame gets stuck and nothing can fix but the restart.
